The Bookshelf function is a great function. I work in a support role for Jisc, who use ProQuest to host our collection of e-books for FE. I have created several Bookshelves to divide our collection into subject and qualification areas, and was disappointed to learn that I would not be able to share these with our members. This is disappointing because it would be a fantastic support mechanism for Jisc's librarian members in the UK. These librarians don't have the time to create these Bookshelves themselves, and therefore this great tool is not being fully utilised. I have had feedback from several members that they would love us to be able to share our Bookshelves. The benefits would be an invaluable support tool for members, and this would increase the usage of our titles because they become easily discoverable for students.
